Video guide on integrating a robot with the roboportal.
Simple robot with rocker suspension and power management system.
Basic example for building arduino-based robot
Minimalistic example of inter process communication with ZeroMQ. The way to integrate with ROS and etc.
Minimalistic robot design for the indoor fun.
Expired by battle bots. To get an idea what is that check the preview below:
Remote controlled vehicle.

The communication between the robot and the user's UI is bidirectional. Data, that could be streamed from the robot to the application and presented on optional widgets:
- GPS coordinates and magnetic heading displayed on the map
- battery voltage
A simple way to play BattleBots online. Toys are remotely controlled over IR with some custom protocol (at least it didn't match existing ones at first glance). Signal is modulated with 38 kHz. The example of 'move forward' command for the robot with address '0':
- 'start' bit ~ 1.7 ms
- 'pause' and '0' ~ 0.3 ms
- '1' ~ 1 ms
- stop 0b00000
- forward 0b10000
- left 0b01000
- right 0b00100
- backward 0b00010
- weapon 0b00001
There are 4 addresses available (0b00 - 0b11)
Parity bit is calculated by counting '1' in command and address. The value is '1' if the counter is odd.
IR led is connected to Arduino (nano in this case) D2 pin thru current limiting resistor 150R.
